The particle characteristics such as size distribution, composition and morphology have been studied in an Fe-20mass%Cr alloy as a function of holding time at 1600°C. The alloy was deoxidised with Ti and Ce, followed by holding at 1600°C and cooling to 1400°C and quenching. The inclusion particles were investigated on a surface of film filter with an open pore size of 0.05 or 5 μm after electrolytic extraction of the metal samples. Different electric charge and electrolytes (2%TEA and 10%AA) were compared for extraction of the Fe20mass%Cr alloy. 300 Coulombs with 10%AA was found most suitable for the electrolytic extraction of particles to determine the particle composition and size distribution. Most of the particles were found to be complex oxides containing Ti, Ce and Cr. Furthermore, the composition of the particles was found to change from a high Ce-content to a high Cr-content with longer holding time at 1600°C.
